- PROCEDURE InitErrMgr(toolErrFilename: Str255;sysErrFilename: Str255;showToolErrNbrs: BOOLEAN);
- { ErrMgr initialization.This must be done before using any other ErrMgr
- routine. Set showToolErrNbrs to true if you want all tool messages to contain
- the error number following the message text enclosed in parentheses (e.g.,
- "<msg txt> ([OS] Error <n>)"; system error messages always contain the error
- number). The toolErrFileName parameter is used to specify the name of a
- tool-specific error file, and should be the NULL or a null string if not used
- (or if the tool's data fork is to be used as the error file, see
- GetToolErrText for futher details). The sysErrFileName parameter is used to
- specify the name of a system error file, and should normally be the NULL or a
- null string, which causes the ErrMgr to look in the MPW Shell directory for
- "SysErrs.Err" (see GetSysErrText).}
-
- PROCEDURE CloseErrMgr; C;
- { Ideally a CloseErrMgr should be done at the end of execution to make sure all
- files opened by the ErrMgr are closed. You can let normal program termination
- do the closing. But if you are a purist...
- }
-
- PROCEDURE GetSysErrText(msgNbr: INTEGER;errMsg: StringPtr);
- (* Get the error message text corresponding to system error number errNbr from
- the system error message file (whose name was specified in the InitErrMgr
- call). The text of the message is returned in errMsg and the function returns
- a pointer to errMsg. The maximum length of the message is limited to 254
- characters.
-
- Note, if a system message filename was not specified to InitErrMgr, then the
- ErrMgr assumes the message file contained in the file "SysErrs.Err". This
- file is first accessed as " ( *ShellDirectory* ) SysErrs.Err" on the assumption that
- SysErrs.Err is kept in the same directory as the MPW Shell. If the file
- cannot be opened, then an open is attempted on "SysErrs.Err" in the System
- Folder.*)
-
- PROCEDURE AddErrInsert(insert: Str255;msgString: StringPtr); C;
- { Add another insert to an error message string.This call is used when more
- than one insert is to be added to a message (because it contains more than
- one '^' character).
- }
-
- PROCEDURE GetToolErrText(msgNbr: INTEGER;errInsert: Str255;errMsg: StringPtr);
- (* Get the error message text corresponding to tool error number errNbr from
- the tool error message file (whose name was specified in the InitErrMgr
- call). The text of the message is returned in errMsg and the function returns
- a pointer to errMsg. The maximum length of the message is limited to 254
- characters. If the message is to have an insert, then ErrInsert should be a
- pointer to it. Otherwise it should be either be a null string or a NULL
- pointer.
-
- Inserts are indicated in error messages by specifying a '^' to indicate where
- the insert is to be placed.
-
- Note, if a tool message filename was not specified to InitErrMgr, then the
- ErrMgr assumes the message file contained in the data fork of the tool calling
- the ErrMgr. This name is contained in the Shell variable ( *Command* ) and the
- value of that variable is used to open the error message file.*)
